SRAM RED eTap AXS 12sp Rear Derailleur Exploring new limits has never been easier with this AXS enabled rear derailleur that's specifically developed for the demands of modern road cycling. It features a high-quality carbon cage material for fantastic strength and durability, without adding any unnecessary weight to your bike. Thanks to its AXS wireless technology, it offers easy personalisation, while its advanced chain management keeps it silence and secure no matter the terrain. Another highlight is it comes with faster pulleys, bearings, motors and signals to improve speed in every way and ensure you're always in the right gear.AXS Enabled Rear DerailleurControl. Personalize. Monitor. AXS is SRAM’s bike component integration system that takes eTap wireless shifting to the next level. The SRAM AXS app allows riders to see battery status, change component behaviour, personalise controls, get maintenance reminders, and update firmware.Super Smooth Orbit TechnologyOn tarmac or gravel, 1x or 2x, eTap AXS gives a quiet, secure, and smooth ride. Thanks to the ultra-lightweight Orbit fluid damper, you’ll ride more confidently and efficiently than ever, no matter the terrain.X-Range Modern GearingRoad bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range offers wider range, more useful and smoother gear progression, as well as smarter shift settings, enabled by AXS.Features: Cage Material: Carbon Pulley Bearings Material: Ceramic Use: Road Speed: 12 speed Cage Size: Short Cage Max Tooth: 33T Battery Included: No, available separatelyTechnologies: X-SYNC: SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. eTap: All of the underlying tech in our new SRAM RED eTap groupset, such as wireless shifting, advanced battery power management, and mechatronics technologies, are meant to serve one ultimate purpose: to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive. Orbit: Orbit technology is an innovative new form of derailleur motion control. It utilizes silicon fluid as part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch system, Orbit technology places no additional resistance on the rear derailleur’s spring when under slow or light movement. This means easier shifting and rear wheel removal. And while riding, the fluid damper reduces chain bounce. It’s rock-solid reliability for both 1x and 2x systems. AXS: AXS is SRAM’s new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware. X-Range: Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.Manufacturer's Part Number: 00.7518.120.000Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
The SRAM XX1 Eagle AXS derailleur carries over many of the features of the mechanical XX1 derailleur, such as the useful Cage Lock and Type 3 Roller Bearing Clutch. Added to this are several all new technologies that help improve performance and durability. Wireless design is incredibly easy to installDerailleur cage is 10mm shorter than regular Eagle derailleurs to improve ground clearanceOverload Clutch helps to protect derailleur from direct strikesType 3 Roller Bearing Clutch provides impeccable chain retentionWater and dust-proof to IP67K to shrug off the elementsControlled by SRAM's new AXS technology, the derailleur offers crisp, instantaneous shifting and a super-clean cable free design, taking mere seconds to install and sync with the AXS controller using the AXS app. Further improving shifting and durability is the Overload Clutch. This works to protect the rear derailleur in case of a direct strike to it from a trail-side obstacle or crash, protecting the derailleur and keeping it shifting smoothly. The pulley cage is also 10mm shorter for improved clearance, further reducing the risk of damage. The system is completely water and dust proof to IP67K, so the elements are shrugged off with ease. The battery is shared with other AXS and eTap components, so can be swapped if needed and lasts between 20-30 hours of riding between charges. SRAM sought to raise the bar with XX1 Eagle AXS and they have succeeded; the XX1 Eagle AXS Rear Derailleur is a breeze to install and provides next-level shifting performance.
